To all whom it may concern.-

Be it known that LALLEN DE ViLBrss, J r., a citizen of the UnitedStates, anda resident of Toledo, Lucas county, State of ()hio, haveinvented certain new and useful Improvements in Computing-Scales, (CaseN;) and my preferred manner of carrying out the in vention is set forthin the following full, clear, and exact description,.terminatin withclaims particularly specifying the nove ty.

This invention relates to scales of that class which compute or indicatethe total weight and total price by a hand standing normally at. 0, butmoved over 'the table by the load and coming to restwbenthe same iscounterbalanced; and the objects of the same are to simplify thecqnstriietion ,of such a scale; to render possible theuse of a tare beamand wei ht in connection there with, and to provi e a li uid-brake'forpre in both these res ects and in ct ier details over my Patent Case A)No. 621,297 and issued March 14, 1899, and it is adapted to theconstructions shown in and yet is an improvement over my two com )anionapplications, of which one (Case B) cars Serial N 0. 703,253 and wasfiled Janna 24, 1899, and the other (Case H) bears Serial No. 737,770and was filed November .21, 1899, and allowed January 24, 1900, theprincipal improvement over both these casesconsisting in omitting thecounterbalance opposite the, linkivot and using an improved form ofliqui -brake.

The following specification describes, briefly, the general constructionand operation and at greater length the improyements and theiradvantages, all as illustrated in the accompanying drawings, whcreirFigure l is a sectional view through one type of my scale, showing thehand as moved to eight pounds and the tare-beam coin lete.

F 1 .2 is a similar sectional view throu g i another type of my scale,showing the hand at 0.--- ligs." 3 andA'are enlarged sectional views ofthe li( uid-brake, the latter sl iowing what occurs w on the device isinverted, as. in transportation, and also illustrating a slightmodification of the )iston. Fig. 5 is a pers eetive detail of the ass,the fulcrum; the cam, and the lower portion of the casing.

hangs rigidly apendulum 8; having a fixed weight 9 at itslower'end. InF} 1 this weight is eolor'edto correspond wit one of the rows ofweight-totals, and thereis an additional removable weight'90 of theothercolor, and there may be a second removable weight 900. Fixed toand.rising from the disk obliquel to thependulum is a fhrablyhavin notches92 in its active face, adi acent whic i are numorals to coaet with theseveral lines of 8o' price-totals. I'n-Fig. 1 there are two rows ofthese numerals opposite the notches, and the rows arecoloredtocorrespond with the two rows of weight-totalsand the twoweights on the pendulum. Projecting from the. disk dihmetricallyopposite the center of gravitv of the hand is a screw 19, on which is anadjustable nut 12, forming a counterbalance for the weight which thehand ossesses when it stands oblique. In the diskat a point between thescrew and the hand is a knifepivot 10, whose edge is normally above thatof the central pivot 7 when the pendulum s vertical and over hich hangsa ink 11, that extends downward and is connected with the scale-beam.

is a tare-beam moving in unison with the main beam and preferablyextending past both ivots 2 and 5. Thetare-beafn an 21 is thetare-weight.

is a cylinder. (see Fi 3) mounted by preference within the boiy portionof the casing about where show and 41 is a rod pivoted to the scale-beamand supportingba piston 42, which may be ad usta e, as y nuts 43,located above and below the same.

a dash-pot 45 of relatively smaller-ca acity and at its upper end achamber 46 oi relatively larger capacity. 47 is a cover closin' theupper end of the cylinder, and hence 0 the c amber, and 471 IS a nipplede endin rigidly from this cover into the chem er and nearly to thebottom thereof, which is the top of the dash-pot. The cover and ni ple;are pierced with an o ening, through which loosely passes the ro 41, andthe piston 42 is eithersomewhat smaller in diameter than the dash-pot,as seen inFig. 3, or=it may have openin s 44 through-its body, as seen1n Fig. 4. E 1t er or. any;r equivalent construction permitspassage tough or by the piston of- Oil or other liquid with which the-.dash-potis evenly filled. When a scale containing this form of cylinder isinverted, theliquid runs out 0t thedashot into the chamber; whosecapacity aroun the ni ple is greater than that of the dashot.- 'encetheliquidthen. stands as seen in ig. 4, andthe necessity-for packingaround the rod is obviated.

The weight 12 counterbalances the hand: 91-, the pendulum with itsweight or weights hangs normally vertical and swings outward into theextension 129 as the disk 96 turns (inits pivot 7,--and the othenpartsare-so aiweightis at 0- they. are'exactl counte -ranged-and proportionedthat when thetarfbalanced over the fulcrum 2. en a 10 d is placed on'thelatform, theinnen end of tlie beam .1 descen s, the link 11 turns thedisr, and the hand 91 moves over the table, whi e the pendulum rises andains wei ht sufficient to balance the load. eanwhi e the piti tondescends in the li uid, and. the densi of the latter causes the and tocome quick 4 to rest.' Hadtheloadbee'nlard,forinstanc ,1. the grocerwould have first placed a crock'qn' the platformand immediate] movedthetare-weight 21 until the ban returned to 0 from the oint towhich theweight of. the crock had moved it. Thereafter the weighing of. thecommodity proceeds as above described.

In Fig. :2-the row 14 ives the total of weight, the figures on the andare the price per ound, and the figure. in the table 30, whic is exposedthrough the notch 92 0pposite theproper price per pound, is the totalprice. In Fig. 1 the same is true with the shaded row 14, the shadedfigures on the hand, and the fixed weight 9;.but when the light weight90 is added the hand will move to a less degree and the light row 140and 'figureson the light portion of thehand must be used, theprice-totals still being found in the proper notches. -The=addit1onalweight 900 increases the capacity be ond. the limits of total figures,as by doub ng them, and when this weight is used those totals must bementally doubled.

What is claimed as new is 1. In a scale, the combination with the mainbeam having fulcrums .mounted on a support, the pan orplatform pivotallysupported upon and carried, by the main beam, and means for reducingvibration of said beam; of an auxiliary or tare beam connected andmoving with the main beam and located beneath the pan or platform, atareweight thereon, and means connectedwith the-main beam forautomatically offsetting the weight of the load.

2. In a-scale, the combination withthe main beam having. fulcrumsmounted on a support; the pan oriplatform pivotally supported uponandcarried bythe main beam, and-means for .reduoingiivibration ofsaid beam;of-an auxiliary or tare-beam connect edzand moving with themainbeamandlocated beneath the pan. or platform-and exdending past themain fulcrum, a tare-weight thereon, and means connectedwith the mainbeam for automatically-offsetting the weight ofthe load.

3.- In a scale, the combination with the computing-table, the main beammounted'on fulcrums carried by a support rising from the base,asupplemental or tare beam connected therewith, a tare-weight thereon,.and a: pan or latform carried by themain-beam; of a hand and pendulum.rigid/with each-other. and mounted on a knife-edge pivot common to both,and connections between one beam. and

In a scale, the combination with themain beam having fulcrums mounted on a support rising from the base, apan or latform carried by said beam, meansfor 0 setting the weight ofthe load, an-upright cylinder containing-a dash-pot, and a n1p leextending downward from theuppenen thereof; of a rod connected with amoving art of the scale mechanism 'and.. passing. osely through thenipple, and a p1ston -on-.the;:rod movingwithin the dash-pot, as and'for-the "purposesetforth.
